摘　　要：型钢混凝土(SRC)柱-钢梁混合框架结构具有较好的抗震性能,在大跨度结构及高层建筑中得以广泛应用,然而对于SRC柱-钢梁混合框架结构的抗震设计方法研究较少。根据SRC柱-钢梁混合框架结构的特点,将其性能划分为使用良好、暂时使用、修复后使用、接近倒塌四个水平,采用层间位移角限值予以量化,并在此基础上提出SRC柱-钢梁混合框架直接基于位移的抗震设计方法。利用通用有限元软件ABAQUS中的PQ-FIBER模型对SRC柱-钢梁混合框架进行静力弹塑性分析,并采用已有的试验研究成果对PQ-FIBER模型的适用性进行了验证。采用此方法对某8层SRC柱-钢梁混合框架结构进行了设计,然后采用静力弹塑性分析法验证该方法的可行性,为SRC柱-钢梁混合框架结构直接基于位移的抗震设计方法提供一定依据。The SRC column-steel beam hybrid frame structure has good seismic behavior,which is widely used in large span structures and high-rise buildings.However,few studies have been performed on seismic design of the SRC column-steel beam hybrid frame structures.According to the characteristics of the SRC column-steel beam hybrid frame structure,its seismic performance is divided into four levels,i.e.,serviceability,temporary use,use after repair,and close to collapse.The four levels is quantified using the inter-story drift ratio limits,based on which the direct displacement-based seismic design method of SRC column-steel beam hybrid frame is proposed.The PQ-FIBER model in ABAQUS is used to analyze the static elasto-plastic performance of the SRC column-steel beam hybrid frame,and the applicability of the PQ-FIBER model is validated by the existing experimental results.Finally,the method has been successfully applied to an eight-storey SRC column-steel beam hybrid frame structure,and is validated by static elasto-plastic analysis.The proposed method herein can form a basis for the direct displacement-based seismic design of the SRC column-steel beam hybrid frame structure.
